John McEnroe of the U.S. reacts after missing a point against Ivan Lendl during their BNP Paribas Showdown friendly tennis match in Hong Kong in this March 4, 2013 file photo. McEnroe faces compatriot James Blake April 1, 2015 in a match in which they will call their own lines-declaring whether the ball is in or out-a wrinkle that McEnroe knows may draw more than casual interest from fans and former linesmen.
